Abstract  Abstract

An ARQ transmitting method in the communication system retransmission according to automatic repeat request wherein data packets comprising modulation symbols and then to a previous received data packet combination. In the mapping entity modulation symbol of the data packet using a predetermined signal pattern (constellation). one version of the form is the retransmission of data packets in a plurality of different redundant version selected for retransmission. According to the invention before the retransmission modulation according to the chosen redundancy version recording packets to be transmitted.

An ARQ retransmission method in a communication sytem wherein data packets comprising modulation symbols are retransmitted based on an automatic repeat request and subsequently combined with previously received data packets the symbols of said data packets being modulated by a mapping unit employing a predetermined signal constellation. The retransmitted data packets being retransmitted in form of a selected one of a plurality of different redudancy versions. According to the invention the bits to be transmitted are recorded prior to modulation over the retransmissions in accordance with the selected redundancy version.
